Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed December 5, 1918. Serial No. 265,391.

To all whom it may concern Be it known that I, FREDERICK V. ANDER- soN,a citizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Presses, of which the following is a specification. Thisinvention pertains to presses, and more particularly to that typewherein a series of spaced bars are employed to form the press body.

The present structure is in a sense an improvement upon the press shownin Letters Patent No. 829,315, granted to V. D. Anderson under date ofAugust 21, 19.06, to which'reference is made, and has to do moreparticularly with the means employed to se-v cure the requisite anddesired spacing between the bars at the inner edges thereof.

- Under the construction set forth-in said patent, several disadvantagesare present:

vfirst, the necessity of' drilling rivet holes through the bars fromside to side, which involves time and consequent expense; second, thebreaking of'the bars in line with the holes (at which point the bars arethe hardest) during the process of straighten.

mg; and, third, the spacing cannot be changed-without first chiselingofli' theold spacers, driving out the rivets and riveting on newspacers.

The present construction has the following advantages over the old:First, itis not necessary to drill rivet holes in any of the bars, or togive them any special form to receive the spacing elements, thus makinga saving in the time required for drilling as well as quite a reductionin breakage during the straightening process which the bars undergo;secondly, the spacers bein removable and interchangeable the width ofthe drainage slots between the bars can be easily changed at any time bysubstituting new spacers of different thickness.

The invention is illustrated in the annexed drawings, wherein,

Figure 1 is an end elevation of a press body in whichthe bars areseparated by the improved spacers;

Fig. 2 a perspective view of several of the bars on a larger scaleshowing the spacers more clearly;

Figs. 3 and 4 perspective views of two of the spacers, that in Fig. 4being thicker than the other; and

Fig. 5 an edge view of one of the spacers.

Only so much of the complete press is shown as 1s necessary to anunderstanding of the present improvement, reference being had to theabove mentioned patent and others to the same party for details of thepress generally.

In the drawings 1 and 2 denote two barrel rings or cross frames, each ofwhich is provided with a semi-circular recess to receive thelongitudinally extending body or barrel bars 3. The series of bars oneach ring or cross frame is held in place by two oppositely disposedframe bars 4 and 5, and an intermediate bottom frame bar 6, to which issecured a key bar 7 The body bars 3 are preferably of the formillustrated, that is their inner faces produce a stepped constructionwith the forward edge of each bar extending inwardly to a slight extentbeyond the rear edge. Such arrangement is, however, not essential to thepresent invention and forms the subject matter of the copendingapplication Serial No. 219,837, filed on or a out March'1st,-19l8.

The bars 3 are separated or spaced from each other to provide drainagespaces and to secure such I employ spacers of the form best shown inFigs. 3 and 4, the two being the same except for thickness of metalemployed in their manufacture. Such spacers may be said to comprise ahead or body 8 and a plurality of arms extending from one side thereof,said arms being preferably three in number, two of such arms 9 lying inthe same plane and inclined or bent out of the plane of the head, whilethe third arm is denoted by 10 and is inclined from the head in theopposite direction. There is thus produced a spacer having a head anddivergent arms, which latter form a Y that extends to one side of thehead. Preferably the intermediate arm 10 will be equal in width to theother two arms combined so as to secure an equal distribution of metal.

The spacers are formed from sheet metal,

the head determining the drainage space be-' are. By using spacers tweeneach pair of with the spacers interposed formed of difi'erent thicknessof metal, the size of the drainage spaces may be readily and accuratelydetermined. Furthermore, the form of the spacer assists in the readyassembling of the bars, the spreading arms holding the bars in theirproper position as they are laid up one above the other as well asserving to hold the spacers themselves in place.

What is claimed is 1. In a press, the combination of a sup portingmember having a curved face; a series of bars mountedthereon; and aplurality of spacers disconnected from the bars and held therebetweention of the bars thereon,

2. In a press, the combination of a supporting member having a curvedface; a series of bars substantially rectangular in shape supportedthereon; and a series of independent disconnected substantially shapedspacers interposed between and clamped by the adjacent faces of the barswhereby drainage spaces will be formed between the inner edges of thebars.

3. A shell or casing for a press, comprising a series of tially circularform; pendent and a series ofindefor a press, comprismg a series of barslaid up in substantially by the binding ac-- bars laid up in asubstandisconnected spacers for the bars held between the inner edges ofthe adjacircular form; and a plurality of spacers formed from sheetmetal, the inner ends whereof are clamped between and held by theadjacent bars, said spacers being otherwise disconnected from the bars.

5. A shell or casing for a press, comprising a series of bars laid up insubstantially circular form; and a plurality of spacers formed fromsheet metal, each of said spacers comprising a head adapted to beclamped between the adjacent inner races of thiebars, and a plurality ofdiverging fingers extending outwardly from the head.

6.- As a new article of manufacture, a spacer for bars for press shells,comprising a head, and a plurality of divergent fingers extending fromone side thereof, said spacer being produced from sheet metal bent toform. I

"7. Asa new article of manufacture, a spacer for bars for press shells,comprising a substantially Y-shaped member, produced from spring sheetsteel, cut and bent tol form.

' 8.As a new article of manufacture, a spacer'for bars for press"shells, comprising a head. and three fingers extending from one edgethereof, the intermediate finger being wider than the outer fingers andin clining or diverging therefrom, said outer fingers lying in the sameplane.

In testimony whereof l have signed my name to this specification.

FREDERICK V. ANDERSON.
